IMPROVEMENT IN MACHINES FOR BENDING PRINTERS LEADS AND RULES.

Specification forming part of Letters Patent No. 124,295, dated March 5, 1872.

Specification describing a new and Improved Machine for Bending Printers Leads and Rules, and other purposes, invented by FRANK 0. SMITH, of New York city, in the county and State of New York, and HENRY MoCoL- LUM, of Long Island City, in the county of Queens and State of New York.

Our invention consists of a roller bendingmachine, in which the adjustable bendingroller is mounted in one end of a long swinging frame, whose other end is at such distance from the roller as to allow of the wide range necessary for adapting the machine to form curves of an yradiuses required for the leads and rules used in printing, and the said swinging frame is supported at the end next the rollers on the temper-screw, by which it is adjusted, the same being a simple and inexpensive arrangement.

Figure 1 is a transverse section of our improved bending-inachine taken on the line :20 x of Fig. 2; and Fig. 2 is a plan or top view.

Similar letters of reference indicate corresponding parts.

A and B represent a pair of ordinary metal rollers, mounted one above the other in housings C, one being movable toward and from the other, and provided with temperscrews 1). E represents the adjustable roller, which we mount in one end of a vertically-oscillating frame, F, at one side of the rollers A B, and pivoted in brackets G of the housings at H, a considerable distance from the said rollers A B, so as to have a wide range vertically for bending the leads and rules used in setting type in curved lines, to curves of any required radius, which greatly vary in this respect. I is a temper-screw for lifting the said rollerframe and letting it fall for varying the curves; It also supports the free end of the frame F. K is a guide, attached to one of the housings at the side of the rollers, where the rules and leads are introduced, against which they are placed at one edge to insure the introducing of them, parallel with the line of their movement. The ends passing through rollers A B are received on roller E above its axis, and turned upward to pass over it. In case the curve is to be on a very short radius which cannot be formed with roller E so low as to thus receive the ends, it may be raised afterward. The roller A is provided with a handwheel for turning.

Having thus described our invention, we claim as new, and desire to secure by Letters Patent The improved machine for bending printers rules, consisting of metal rolls A B, housings O, temper-screws D, roller E, oscillating frame F, brackets G, housings H, and screw I, when all are constructed and arranged substantially as and for the purpose described.
